Least I found out early on...
You see, I had an idea for this "paratrooper" system where the hydras would go into lurker eggs, and then when the player was ready, cast some spell or something, teleporting the eggs to wherever they need to be paradropped (and probably having some sort of effect to spread them out), and then the player could cancel the lurker eggs and have the hydras attack.
It needs to be able to detect the eggs, because 1.) lurkers are already being used for other purposes and 2.) they have to be in their little pods and immobile throughout the process (it wouldnt make sense if the lurkers could move around or attack and such).
However, apparently, triggers can't detect lurker eggs.
Anyone got any ideas for alternative methods I could use for an idea like this? (note: the unit doesn't have to be hydras, but I'd prefer it'd be either zerg or protoss ground unit with a ranged attack)
None.
